Question / Help Can I stream with my setup?

Hi guys,
I just wanna ask if I can stream with this kind of PC
GPU - GT 730 Nvidia
CPU - AMD A8-8650 Radeon R7 3.20 GHz
RAM - 16 GB
Internet speed - Download 92,84 Mbit/sec Upload 93,42 Mbit/sec

I am not sure if that's everything. Probably I am missing something, but these are the mains in my question. I really wanna try streaming but I am not sure if I really can.
I am new in this kind of thing and I am not sure how to set it up properly.

Thank you and sorry for asking.

Not all GT 730 cards have hardware encoding. If you could download GPU-Z and either post a screenshot or you looks for if it is model gf108 (Fermi no Nvenc) or gk208 (Kepler yes Nvenc). Your hardware is pretty weak so if you are trying to game and stream at the same time, taking reducing cpu usage with Nvenc hardware encoding would help immensely.

Other tips are to update the the newest version of windows. Turn off game dvr and game bar. Turn on Game mode (only on newest windows update). These steps will help with both gaming and encoder performance.

Lastly, please use this software to test your upload speed to actual Twitch servers.

According to the log, nvenc is available, because there is a successful streaming session with nvenc in the log. It's even the "new" nvenc variant, so it's the most efficient configuration.
The log shows a bit rendering lag and a bit encoding lag. That means OBS is scratching at the upper limit what is possible with that hardware. Turning off game dvr and game bar might help a bit. Also might help to set psycho aq to false in the nvenc encoding settings.

The connection to Twitch is ok and does not need to be assessed, since there are no lost frames due to bandwidth issues in the log.

The rendering and encoding lag visualizes itself in the stream as choppy and not fluent video stream. The amount of lag indicates that there is about one lost frame per second. This can be clearly seen. This might be acceptable due to the low performance hardware. If it is not acceptable, and disabling the things mentioned above do not help enough, the most promising workaround would be to lower the output resolution (or both canvas and output) from 720p to some lower settings such as 480p (854x480).
